JY 20, 1948- w. TRQGMAN BOX FASTENING MEANS Filed Oct. 14, 1944 PatentedJuly Z0, `1948 UNITED STATES PATENT OFFICE Y 2,445,412V y 1 I BOXFASTENING S William Trogman, Chicago, lll. Application October 14, 1944,Serial No. 558,655 1 Claim. (Cl. 229-47) This invention relates toboxes, especially oi the type known as merchandising boxes, in whichthere are two box sections arranged in intertting latched relation withrespect to each other and provided with a handle to facilitate carryingthe box about.

The invention has for its principal object the provision of an improvedconstruction of this character which will be highly efficient in use andeconomical in manufacture.

One of the principal objects of the invention resides in the novellatching means for box sections.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings showing the preferred form of construction, and in which:

Fig. l is a perspective view of the box embodying my invention showingthe same in a partially open position;

Fig. 2 is a perspective View of the same showing the box sections ininterfltting relation;

Fig. 3 is a fragmentary top plan detail view, partly in section of thesame taken substantially on line 3-3 of Fig. 2;

Fig. 4 is a fragmentary sectional detail view of the same takensubstantially on line 4-4 of Fig. 2; and

Fig. 5 is a fragmentary sectional detail view of adjacent wall sectionsof the box showing the relationship of the latch structure with respectthereto.

Referring more particularly to the drawings, my improved box comprisestwo interiitting box sections I0 and II, the box being indicatedgenerally at I2. The Isection I0 has a wall portion I3, and in this wallportion I3 in a direction from the edge I4 thereof is formed a recess I5from which preferably though not necessarily are two lateral recessesI6.

The section II has a wall portion I1 provided with a slot or slit I8through which is hooked a handle bar I9 having lateral extensions 20which engage beneath the wall I1 when a box is being carried about.

The reces-s I5 provi-des a tab i8 which preferably, though notnecessarily, is insertable through the slit I8 whereby to provide areinforcement for the adjacent portion of the wall I1 which receives thegreatest strain due to a weight in the box when the box is being carriedabout by the handle.

, tion set forth,

Formed in the wall I1 are oppositely disposed slits or apertures 2I, andthese slots or `apertures 2|, which may be referred to as slots, are inregistration with the slots or lateral recesses I6, which likewise maybe termed slots.

The box sections when arranged in interfltting relation are releasablylatched together by means of oppositely disposed latches 22. Each ofthese latches 22 is substantially U-shaped in form, with the limb 23thereof insertable through the adjacent registering slot-s I6 and 2I.The opposite limb portion 24 is provided with a iinger piece 25 whichfacilitates removal of the latch from a latched position, and this limbportion 24 is provided with a kink or rib 25 which bears against theadjacent portion of the Wall I3.

The latch is formed of spring material so as to frictionally embraceadjacent portions of the wall I3 and I1. To assist in this frictionalcontact between the latch and the adjacent walls I3 and I4, in formingthe slot 2| a spring tab 21 results, and this tab, as Ishown in Fig. 4,bears against the adjacent limb 23 and thereby assists in frictionallyretaining the latch in position.

In carrying my invention into effect, it is to be understood that theshape, size, number and location o-f the slots I6 and 2l are not inlimiting character and should not be considered as such. This is alsotrue with reference to the form of the limb portion 24 and the materialfrom which it is formed, except that it is desirable that the latch beU-shaped and be oi resilient material. The latch may be formed of roundor flat material and in such la manner so long as it frictionallyembraces adjacent portions of the walls I3 and I1 for the purposesherein stated. By the same token the construction of the box sections I1does not enter into my invention, as the construction of these boxsections, and especially the manner in which they are hinged orotherwise attached together for movement from and into interiittingrelation, may vary in form and design as well as structure withoutdestroying the utility and usefulness of my invention.

While I have illustrated and described the preierred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, `do not wish to be limited to the precisedetails of construcbut desire to avail myself of such variations andmodifications as come within the scope of the appended claim.

Having thus described my invention, what I 3 claim as new and desire toprotect by Letters Patent is:

A box comprising two interfitting box sections with a wall of one of thesections providing a recessed area and a Wall of the other section aslotted portion providing a yieldable tab, means for latching the boxsections in ntertting relation with respect to each other with therecessed area in said one of said sections in registration with the V Ysection, said means comprising a resilient substantially U-shaped memberremovably mounted and frictionally engaging adjacent portions of.

the said walls, the tab provided by said slotted 15 portion frictionallybearing against said member.
